Due to the unprecedented events of Covid-19 pandemic and the lockdown regulations that were introduced by the government, online shopping became much more popular than it used to be, before the pandemic. This is because people needed to use the online shopping quite frequently for safety measures by keeping social distancing and avoiding overcrowd. However, as much as online shopping was a positive solution for shoppers, online criminals saw this as an opportunity to defraud people using crimeware such as identity theft, cloning of bank cards, and electronic stealing of money. Crimeware can spread by way of viruses, Trojan horse programs, worms, spyware or adware. Due to Covid-19, a higher number of people needed to stay indoors more, hence the need for the use of online shopping to buy groceries and other necessary goods has greatly increased. This rapid increase of online shopping has led to more people prone to cybercrime. However, the effect of Covid-19 lockdown regulation on online shopping cybercrime, especially in the developing nations, where computer security literacy level is still low, remains a research issue that needs to be addressed. Hence, this study investigates the effects of Covid-19 on cybercrime in online shopping using Buffalo City as a case study.
